Question

Which expression is equivalent to the one shown below (427-30) A 121 B. 120 C. -12° D.-126

Answer 1

Given the expression:

`(4x^2)(-3x^3)`

Multiplying the coefficents 4 and -3 give -12

Multiplying the variables by summing the exponents

So,

`\begin{gathered} (4x^2)(-3x^3)=(4\cdot-3)x^(2+3) \\ \\ -12x^5 \end{gathered}`

So, the answer will be -12 x^5
